Isaiah 4:4-5

4At that time the sovereign master will wash the excrement from Zion’s women, he will rinse the bloodstains from Jerusalem’s midst, as he comes to judge and to bring devastation.

5Then the Lord will create over all of Mount Zion and over its convocations a cloud and smoke by day and a bright flame of fire by night; indeed a canopy will accompany the Lord’s glorious presence.
